Although the present invention has been described with reference to the embodiments shown in the drawings, it is to be understood that the technical idea of the present invention and its essential structure and operation are not limited thereby. In the present specification, "rearward" means a direction in which the vehicle collides against the support body, i.e., a direction in which the vehicle approaches and moves toward the support. That is, the direction of arrow K in Fig. 2 becomes "rearward ". Therefore, in the present specification, "forward" means a direction in which the vehicle looks at the vehicle from the supporting body when the vehicle collides against the supporting body, that is, the direction opposite to the rear. And "longitudinal direction " means the direction leading to the front-rear direction, and" lateral direction " means the direction perpendicular to the longitudinal direction in the plane.
